I suspect we'll over rotate, and use Bush far too seldom in power running formations. That's the tendency in a situation like this, particularly with a coach from Green Bay and such recent success on a pass oriented team. He won't fully grasp that it wasn't the formations and schemes and brainpower as much as simply a dominant quarterback like Aaron Rodgers, allowing everything to unfold better than any birthright.
Likewise, a tipoff will be when we use Matt Moore too often in empty formations, and they will be avalanched. Great quarterbacks can get away with empty sets but it's exponentially less effective as you drop in class.
Philbin is a sharp guy and no doubt will adjust but it's a considerable favorite he'll be shell shocked early when all the cute designs don't develop as anticipated, with a moderate quarterback and surrounding personnel.
Bush was thrilled when Daboll had so much patience with him last year, continuing to use power sets out of basic I formation even when it stalled early in the year and even later in the season in his first handful of touches. The Buffalo game was ugly before he busted up the middle several times. Sean Payton was the type to give up on Reggie when games started that way, and I hope Philbin doesn't follow suit. If so, Reggie might opt elsewhere in 2013. We shouldn't discount how much he believes in his rightful place as a full time player.
I've called for Reggie to be used in lethal downfield situations. It needs to be shifts and motion, like lining him up at tailback then darted into the slot, creating confusion and matchup difficulties. If we simply send him out sporadically at wide receiver I think he'll be neutralized and essentially wasted as a decoy, the Sean Payton specialty.
